Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Sulfo-.Omega.-(Nonylphenoxy)- is a high-performance nonionic-anionic surfactant, widely recognized for its excellent emulsifying, dispersing, and wetting properties. This chemical is essential for formulators seeking to enhance the stability and performance of complex aqueous systems. It is a critical raw material for manufacturers in the agrochemical, textile, and industrial cleaning sectors, where reliable surfactant performance is paramount for product efficacy.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (ECs, SCs) and adjuvant systems.
• Textile Processing: Used as a wetting agent, scouring aid, and dye leveling agent in fiber treatment and dyeing baths.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and hard surface cleaners.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Paint & Coating Additives: Enhances pigment dispersion and stabilizes water-based paint formulations to prevent settling.
• Oilfield Chemicals: Employed in drilling muds and production chemicals as an emulsifier and viscosity modifier.
